ELECTRICALICO MMUNICATION.

SPECIFICATION forming part of Letters Patent No. 483,619, dated August 5, 1890.

Application filed March 8,1889.

To all whom it may concern.-

Be it known that I, JAMES L. CUTLER, a citizen of the United States, residing at Piketon, in the county ofPike, State of Ohio, have invented a new and useful Improvement in Electrical Communication, of which the following is a specification.

My invention relates to the art of electrical communication by means of a series of sig nals or other devices connected with and operated from a central station, and its object is to provide mechanism whereby each of a serles of visual, palpable, or audible signals at various points on a main circuit may be operated or called into action or other work performed from a central station without operating or calling into action the signals or performing the work at other points or stations on the same circuit. This I accomplish by means of a regulating-instrument at the local or relay station, which may be actuated from a central station by making and breaking the main circuit, so constructed, arranged, and operated that the signal or machine to be operated at that station will respond to or be actuated by the call for that station and will not respond to or be operated by other calls.

Referring to the drawings, Figure 1 is a top View of one of my improved regulating-instruments. Fig. 2 is a section on line 2 2 of Fig.

1. Fig. 3 is a section on line 3 3 of Fig. 1. Fig. 4 is a side elevation of the regulator or permutation wheel. Fig. 5 is a diagram of the circuit-connections. Fig. 6 is a diagram of the path, relative to the periphery of the permutation-wheel, of a movable pin.

I introduce into a main circuit at the various stations where a signal is desired relays, local batteries, and one of my regulating-instruments. The main line is connected at each local station with-a relay and the relay with posts 1 and 2.

A and A are local batteries.

B, B, and B are electro-magnets. The armature b of magnet B is attached to a lever O, mounted upon a spindle c and adapted to which is also provided with a non-conducting set-screw d. To the free end of this lever is Serial N0. 302,521. (N0 model.)

pivotally attached a pawl E, adapted to actuate a permutation-wheel F and provided with a non-conducting joint 6.. Ihave illustrated the permutation-wheel as fixed upon a spindle f, which carries a ratchet-wheel f, with which the pawl E directly engages. The spindle f is supported in suitable bearings Gand G, and also carries a grooved pulley f over which takes a cord f carrying a weight f. It is obvious that a spring might be used in place of and as the equivalent of the grooved pulley and weight.

The armature b of magnet B" is attached to a lever O, mounted upon a spindle o and pivotally attached at its free end to a hooked pawl E, adapted to engage With and actuate the ratchet-wheel f in the same direction in which it is actuated by the pawl E. The magnet B is preferably of higher resistance than magnet 13 and the armature l) heavier than armature b, and'the magnet is so provided with adjusting devices that its armature will only respond to a firm dash.

' His a pawl adapted to prevent the ratchet- Wheel from turning backward. The pawls E E may be forced into engagement with the ratchet-wheel by springs 6 6 I is a standard carrying in suitable bearings a live spindle J, having mounted thereon an arm K, carrying a hinged tongue 70, which normally rides in close propinquity to, but not in electric contact with, the permutationwheel.

L is a non-conducting arm fixed to the spindle J and carrying at or near its free end 8 5 a pin Z, adapted to take into a slot a in a plate 6 upon pawl E.

' The permutation-wheel is provided with a series of lugs or pins or projections f and a series of ledges or projections f extending 9o sufficiently above its periphery to engage with the tongue 71; under conditions which will be more fully explained hereinafter. The permutation-wheel is also provided with pins or lugs f and f the former adapted to engage an arm 97?, preferably a spring-arm, upon a standard M, and the latter adapted to engage with a standard N.

O is a switch-key adapted to engage With posts 7 and S, and P is the signal or mechanroo ism to be operated.

(Shown as a bell.) The armature b of magnet B is attached to a bent lever having itsfulcrum upona spindle 0 carried by a standard Q. One end of lever (1 1s adapted to engage a non-conducting arm g, pivoted to standard G and taking under the pawls E, E, and H, for the purpose of lifting them out of engagement with the ratchet-wheel. This lever also carries a spring arm 0 adapted to engage a set-screw r in a standard R, when the armature b is attracted by the magnet 13 1, 2, 3, 4, 5, 6, 7, S, and 9 are binding-posts. The instrument is provided with the ordinary springs, adjusting devices, &c. The coils of magnets B and B are preferably horizontal and those of magnet ]3 vertical. Magnet B is connected with posts 1 and 3, post 3 with post 2, lever O with 4 sponding space.

post 4, magnet B with standard D and post 5, post 5 with post 4:, magnet B standard N, and post 9, standard M with switch-key 0, post 6 with magnet 13 standards Q and I, and post 7, post 8 with post 9, and post 4 with standards R and G. Local battery A is on the line 2 3, battery A on the line 4 5, and the signal or machine to be operated on the line 8 9. Y

hen the sending-inst-rument at the central station is operated by depressing the key, the relay will respond, and a circuit I is formed through post 2, battery A, post 3, magnet B, and post 1, and the armature Z) will be attracted by the magnet B, carrying with itthe lever O. ,The pawl E will move with the le- Ver 0, and being in engagement with the ratchet-wheel f will move it one space, thereby moving the permutation-wheel a corre- OircuitIwill be formed and operate magnet B and its armature and lever either by a dot or a dash. Circuit 11 will be also formed either by a dot or a dash, as lever 0 must necessarily come in contact with set-screw (Z, thus completing (whenever circuit I is closed) circuit II through set-screw (1, standard D, magnet B, post 5, battery A, post 4, and lever C; but owing to the momentary contact of set-screw (l and lever O, the heavy armature B, lever C of magnet B with its adjustment, will not respond except when a firm dash is made. Vhen circuit 11 is formed by a dash, the movement of the armature b draws with it lever O and pawl E, thereby moving the ratchet-wheel and permutation-wheel one space in the same direction 1n which it has been pushed by the pawl O. ,The same movement of the pawlE which actuates the permutation-wheel also draws the arm L, thereby oscillating the spindle J and swinging arm K, carrying the tongue k.

Each signal or machine is designed to respond to a series of pulsations which may differ from that responded to by each or any of the other signals or machines on the line, the particular series to which each signal or --machine responds being determined by the arrangement of the pins and ledges 011 the permutat1on-wheel, which arrangement can be varied to a practically unlimited extent. The periphery of the permutation-wheel is divided into spaces corresponding with the ratchet-notcl1es. The pins f are placed upon the periphery of the wheel at such intervals as to engage with the tongue if the regulator-wheel be rotated more than the desired space while the arm K is in its position of rest. The ledges f are placed within the range of movement of the tongue 76 in such manner that they will engage with it if it be drawn out of its position of rest when such movement is not required for the purpose of calling into operation the signal or machine connected with that instrument, but will not engage with the tongue 7a when it is properly moved to call the signal or machine into operation. This will be better understood by reference to the diagram shown in Fig. 6 of the drawings. The call for the instrument illustrated is dot, dash, dot, dot, dash, dot, dot,

dash. The pins f are placed so that they must be passed by the tongue 70 when the dashes are made.

Recurring now to the action of the permutation-wheel when driven by the pawls E and E, it will be seen that the wheel is moved one space by the depression of the key for the dot. Upon the next depression of the key for the dash the wheel will be moved one space in the same direction by the pawlE and another space by the pawl E, and the first of the series ofpins f would engage with the tongue 7tif the pin remained in its position of rest; but when the dash is made the tongue 70 is drawn out of line with the pins f by the action of the arm L. The ledges f are so arranged that the tongue kwill swing into a space between two of the series when the dash is made at its proper place in the call for the signal or machine connected with the instrument. In this manner when the proper call is made the tongue 70 is automatically kept from contact with the pins and ledges, as indicated by the linezz in Fig. 6, on which the dotted portion indicates the positionr of the tongue 70 relatively to the periphery of the wheel during the travel of the wheel caused by the dots and the unbroken portion its position during the travel caused by the dashes, and the wheel continues to rotate Without engaging with tongue 70 until the call is complete, when the lug f 7 engages with arm m on standard M and a circuit III is formed through arm m, standard M, switch-key O, (which is set in contact with post 8,) post 8, the bell P, posts 9 and 5, battery A, post 4, standard G, spindle f, and the regulatorwheel, thereby rin gin g the bell or operating the signal or machine. This circuit may be broken at the local station by turning the switch-key. If the switch-key be brought into engagement with post 7, another circuit IV will be made through posts 7 and 6, magnet Bipost 5, battery A, post 4, standard G, spindle f, the permutation-W11eel, arm 4%, standard M, and the switch-key.

IIO

The movement of the armature 12 toward its magnet will actuate the lever C thereby raising the arm g and lifting thepawls E, E, and H out of engagement with the ratchetwheel f, and the permutation-wheel will be moved by means of the Weighted cord f thus arm an.

moving the lugf out of engagement with the As this circuit is broken as soon as the regulator-wheel moves, other means are required to complete the work of this circuit and hold the pawls out of engagement long enough to allow the permutation-wheel to return to its normal position. Vhen the lever O engages with the arm g, the spring-arm c engages with the set-screw r in standard R, and a circuit V is formed through standard R, post 4, battery A, post 5, magnet B post 6, standard Q, spindle c lever 0 arm 0 and set-screw r. This holds the armature on its magnet, thereby holding the pawls out of engagement with the ratchet-wheel until the permutation-wheel has returned to its first position, when a new circuit is formed to break the one just described. hen the permutation-wheel reaches its first position, the lugf engages the standard N, and a circuit VI is formed through standard N, post 5, battery A, standard G, spindle f, the permutationwheel, and lug f Asthis circuit passes through no coil or other medium of high resistance and circuit V passes through a coil of the electro-magnet, the current will pass through circuit VI, and the armature b will be released, breaking circuit V and permitting the pawls to again engage with the ratchet-wheel.

If a dot or dash be made out of its proper place in the call, as in making the call for some other station, or be an error of the operator, a pin or ledge 011 the permutationwheel will engage with the tongue 70, and a circuit VII will be made through tongue is, arm K, spindle J standard I, post 6, magnet B post 5, batteryA, post at, standard G, spindle f,and the permutation-wheel. The movement of the armature b and lever G lifts the pawls E, E, and H out of engagement with the ratchet-wheel, and the perm utation-wheel will be rotated by the action of the weighted cord f", breaking the circuit, when circuits V and VI are again made and the instrument is reset by their action, as before described.

Any instrument may at any time be reset for its call by the operator at the central station making one more, dash in succession than there is in any sequence in the call for the instrument desired to be reset. I prefer to so arrange each instrument that its signal will begin with a dot or series of dots, and the instrument will be reset by the circuits and in the manner hereinbefore described.
